The best rotors are quiet and have plenty of braking surface. Oddly, very few rotors meet this criteria! Long slits in the metal are preferred to random cut outs that are big, as they don’t ever grab pads and make a chattering sound / feeling. Yes, that’s a big thing, depending on pad shape and size. There are only a few rotors out there with long slits, and this is the best one of the money.  Enough braking surface for any style of riding. One of the quietest rotors on the market. Comes with bolts

Rever makes these rotors for Jagwire, and Jagwire in turn sells them to you at a hefty mark up.  Get the factory rotors, same product, less money!  

Made of stainless steel in Taiwan.

Sold without Disc Brake Mounting Bolts
